Problems solved by technology

[0004] In the traditional processing process, it is limited to improve the flavor absorption of shredded leaves by adjusting the processing parameters of the equipment
A large number of experiments have shown that for medium and high-grade high-quality leaf silk, when the process gas treatment temperature is higher than 100°C, the aroma of the dried leaf silk will be significantly worse, and the amount of aroma will also be significantly reduced. Obviously, only by adjusting the existing drying The process parameters in the method cannot meet the lower processing intensity requirements, and cannot meet the quality requirements of leaf shred moisture and odor absorption at the same time
On the other hand, neither the convection drying method nor the drum drying method can simultaneously solve the prominent contradiction between reducing the moisture content, temperature fluctuation and improving the silk filling capacity.
Specifically, the airflow drying method uses a process airflow above 130 ° C. Although it can significantly improve the filling capacity of the leaf silk, the moisture content and temperature of the leaf silk after treatment fluctuate greatly, and the uniformity is poor; the drum drying method is mainly through The temperature of the cylinder wall above 140°C is used to dry the shreds, although it can reduce the moisture content and temperature fluctuation of the outlet shreds, but it cannot achieve a better filling capacity

Abstract

The invention discloses a shredded leaf drying process in the cigarette processing process, which consists of two steps. The first step is to balance the moisture content of the cut shredded leaf to 20%, and introduce it into an airflow dryer. The first zone of the airflow dryer The temperature of the process gas is controlled at 80-100°C, the temperature of the process gas in the second zone is controlled at 70-90°C, and the leaf silk with a moisture content of 20% is dried to about 14-16%; the second step is to import the dried leaf silk into the drum The drying process is carried out again in the dryer, and the temperature of the cylinder wall is controlled at 70-80°C, so that the moisture content of the dried leaves is 12.0-13.0%. Adopting the technology of the present invention can not only improve the moisture uniformity and temperature stability of the processed leaf shreds, significantly increase the filling capacity of the dried leaf shreds, but also reduce the loss of the aroma of the shredded leaves, so that the tar content of cigarettes, smoke nicotine, etc. The amount of harmful ingredients such as the amount has been significantly reduced.

Description

technical field [0001] The invention relates to a material drying process, in particular to a leaf shred drying method in the cigarette processing process. Background technique [0002] Drying is the most important production link in the cigarette processing process. Its basic task is to remove part of the moisture in the tobacco material, improve its filling capacity and processing resistance, and at the same time improve the flavor of the tobacco material and reduce irritation and miscellaneous gas. [0003] There are two main drying methods for tobacco materials. One is the convective drying method, which achieves the purpose of drying and dehumidification through convective heat transfer between the high-temperature air flow and the leaf (stem) silk. The other is the conductive drying method, which achieves the processing quality requirements through the slow conduction between the drum wall and the leaf silk. Regardless of the airflow drying method or the drum drying m...
